Just saw video for gl 1800 ECM repair ( code 25 -26 )may also work for st 1300 . Look up guy called. adventure -alexander on YouTube fresh video.he cuts open and replaces 2 soldered in electric parts
Are you familiar with what he was doing? did you watch video,he mentions other guys that have more knowledgeThis does not fix or repair it, it simply hides the fault light.
He does replace the internal knock modules. not for the faint of heart. Does not give part #This does not fix or repair it, it simply hides the fault light.

If that's the goal, you could just remove the bulb or clip the wires to it.This does not fix or repair it, it simply hides the fault light.
Are you thinking of the attempts that were made by adding additional ground paths to the ECM circuit believing that the fault was due to electrical noise in the ground circuit?The other guys were just members of a goldwing forum, who a few years back, were trying to figure out a fix etc.
They never did.
Folks have been trying this on goldwings and jet skis, to no avail.
It destroys the ECU, and only hides the warning light.
This fixes absolutely nothing.
Folks who build these boards never found a fix for them, but if you want to listen to a couple YouTube videos and destroy what is left of your ECU, it’s a good video to watch![]()
Or put electrical tape over the light on the dashIf that's the goal, you could just remove the bulb or clip the wires to it.![]()

No, as our older members have been around a long time and watched all these attempts to “fix” a damaged ECU and know that nobody was ever able to come up with a fix, all the new folks are coming from YouTube videos and Facebook and just keep “finding” these “new” fixes.A

This is not that. This is replacing the actual knock sensor modules in the ECM. This is the first time that I have been made aware of this repair so I have no idea if it works or not, I'm just wondering if you were thinking that it was the same old ground path repair that was tried and didn't seem to have much success.
But, But, But! I have found an actual and factual way to eliminate the knock sensor codes on my Gold Wing trike! All I had to do was replace the ECU with a NEW one and the codes went away, over a year now and no codes! This must be a real fix!No, as are older members have been around a long time and watched all these attempts to “fix” a damaged ECU, and know that nobody was ever able to come up with a fix, all the new folks are coming from YouTube videos and Facebook, and just keep “finding” these “new” fixes.


Sorry Larry, but as a tired electrician, that is not an authorized use of genuine electrical tape. Off label use, perhaps, but we would all prefer you use masking tape or duct tape.Or put electrical tape over the light on the dash![]()
Where in that ad does it state that the ECU had been repaired and failed? I read that to mean it has the fault and the seller doesnt want to buy a new ECU, maybe unaware that it may be fixable.I’m seeing a lot of F6B, valks, and wings selling really cheap because of these failed repairs.
Just saying…
Larry, call or contact Fred H on GL1800riders. He has relevant recent personal experience with knock sensor ECU repairs. The repair is $300. I know you used to be a member on that site from some old posts of yours and you might remember Fred. I’m on that site nearly daily and I am not familiar with owners commenting on failed repairs. It’s worth going beyond the experience of some stranger selling a Goldwing. I know you really like to help people and if there’s new information that you’re not familiar with you’re selling yourself short.Nowhere, I called and talked to the guy selling this bike. He's an active member on the Goldwing site, and has two GL1800's.
He had the bike inspected by the Honda dealership and verified that the ECU was defective.
After researching many claims of repaired ECU's and possible fixes, he finally gave up, because many of the folks on several of the GL1800 forums who've tried these fixes, eventually ended up right back where they started from again.
So he decided to just give up and sell the bike.
